Web1 Apr 2024 · The production of phenol and caprolactam is the most common use for benzoic acid. Here is the reaction: C6H5CO2H + 1/2 O2 → C6H5OH + CO2 Phenol can be converted to cyclohexanol, which can be used in nylon synthesis. Phenols can also be used in household cleaners and in mouthwash as a disinfectant. Plastics WebFor example, the melting point of pure sucrose (table sugar) is 185 o-186oC. This means that as a small sample of sucrose is slowly heated some of the crystals begin to liquefy at 185o ... pure benzoic acid has a melting point of 122-123 oC, while an impure sample might have a melting point of, say, 115-120oC. The third is to use a physical ...
